WebHow PCIe Low Power States and NVMe Technology Features Achieve Near Zero Power Idle Power. L1.1 and L1.2 are aggressive low power states of PCIe specification. Traditional L1 states allow the reference clock to be disabled on entry to L1, which was shown to consume too much power due to leakage. WebPCI devices might not be in the right states without dis-abling interrupts on the CPU. Moreover, the ACPI spec-ification1 wants us to put devices into low power states before calling the platform firmware to prepare itself for the system power transition and we had to take this into account as well [ACPI-SPEC]. Consequently, to meet
